I have a Hypertech stage 2 chip, with the thermo, replacement. Put it in fine, car works great. My cars an auto and when i drive at idle speed, ie Cruising at 50. the car upshifts then downshifts, up shifts then downshifts, it continues to do this unless i drive faster. hey I wonder if I could use this as an excuse if I got pulled over for speeding? Any idea what's causing this? Never had the problem before, and it doesn't feel like any kind of slippage. _________________

I found a bounty of information on how to and where to get. I have already ordered some stuff. I'm not going too radical, just a chip, cold air, and the throttle body bypass. That should be good for a start. Thanks for the great site and excellent information guys!

Any idea what's causing this? Never had the problem before, and it doesn't feel like any kind of slippage. is that 50km/h sounds like its the torque converter locking and unlocking, i can make mine lock around 50km/h but if i move the gas pedal a little too much it unlocks, that sounds to me exactly what your problem is, im sure you could get your chip reflashed to lock the TCC at a little higher speed and avoid this problem
